Dural Durabase is the same thing (by the same company) but can be found cheaper. You use tile adhesive to stick it down, but generally only in situations where the subfloor is likely to move about a lot, like a wooden floor in a bathroom. A properly dried floor screed doesn't move about a lot. If you're building a ell insulated house the UFH won't run at high temperature either (mine runs at 22 degrees)
I agree with MW's assertion that it would not be needed on a tiled floor, but you're paying the tiler to install your tiles, why are you asking "some bloke on the Internet" how to do his job?
